What does heat exchanger do in oil refinery?
Heat exchangers play an important role in processing oil and gas. They are used in the refining process in cracking units as well as in the liquefaction of natural gas. Cracking is the process of breaking the hydrocarbons that compose crude oil into smaller pieces, according to Chemguide.
What is heat exchanger and types?
There are three main types of flows in a spiral heat exchanger: Counter-current Flow: Fluids flow in opposite directions. These are used for liquid-liquid, condensing and gas cooling applications. Spiral Flow/Cross Flow: One fluid is in spiral flow and the other in a cross flow.
What are shell and tube heat exchangers used for?
Shell and tube heat exchangers are widely used in applications, which require cooling, or heating large volume of process fluids or gases. There are a number of different types of shell and tube heat exchanger designs to meet several process needs in virtually every industry.
What are heat exchangers made of?
Generally, the two most commonly selected materials for heat exchangers are aluminium and copper. Both metals have the optimum thermal properties and corrosion resistance to make them ideal choices, with most of the differences being application-specific.
What is heat exchangers with examples?
A heat exchanger is a device that facilitates the process of heat exchange between two fluids that are at different temperatures. Air preheaters, economizers, evaporators, superheaters, condensers, and cooling towers used in a power plant are a few examples of heat exchangers.
What is an example of a heat exchanger in a refinery?
The classic example of a heat exchanger is foun d in petroleum refineries. Oil Refinery is an industry which r efines liquefied petroleum gas by ] fractional distillation.
Apart from oil industries Shell and tube heat exchangers (STHE) are widely used in many industrial areas, such as power plant, chemical engineering, food processing etc. … …
How are crossflow heat exchangers used in industrial processes?
Crossflow heat exchangers drive the heated process fluid and coolant in directions that are perpendicular to each other. The application of heat exchangers in industrial processes is critical to ensuring optimal productivity. In the oil and gas sector. Where are heat exchangers used across the industry?
What is the purpose of a kettle type heat exchanger?
Also this type of h eat exchanger is easy to clean and test for performance enhancements purpose. exchange between crude and naphtha. It increases the temperature of crude. It is used to preheat the heat exchange r before sending it to crude disti llation column. Fig. 6. Kettle type heat exchanger exchanger.
